Origin: The sixth town to be granted from the Masonian land purchase of 1746, Newton was originally part of South Hampton. Residents in the western portion felt they were too far away from the South Hampton church and meetinghouse, some having to travel 14 miles, and petitioned for a parish of their own. The town was incorporated as New Town in 1749 simply because it was a new town. The church built by these residents was the first Baptist church in New Hampshire. In 1846, the New Hampshire legislature voted to contract the name to Newton.
